    19 Important things to know about the Donsol whale shark experience

    1. The rules of the “whale shark interaction” protect whale sharks and are important to keeping this adventure option alive.  Because of this, be sure to know and follow the rules
      • NEVER touch the whale sharks
      • Maintain a distance of at least 3 meters
    2. Donsol is the most eco-friendly whale shark tourism option in the Philippines and one of the best in the world – a very natural, responsible way to experience the giants.  Supporting ecotourism in Donsol encourages other sites (like Oslob) to follow suit and choose sustainable ecotourism practices
    3. Profits from whale shark tourism in Donsol go to whale shark conservation and community development
    4. Booking a whale shark experience in Donsol is much cheaper than online, but beware in high season as seats may fill up fast
    5. Virtually any time is good to experience whale sharks in Donsol, but December to May is best and ideally February to April offer the best chances of seeing and swimming with a whale shark in Donsol
    6. There is a chance, that you won’t see a whale shark, as whale shark interactions aren’t guaranteed
    7. Whale sharks aren’t dangerous – they’re docile “little” water puppies, as long as you keep your distance
    8. Get fins to improve your experience with the sharks!  The sharks swim quickly when they want to move on, fins will help you keep up.  Additionally, fins allow you to dive down, getting a great vantage point
    9. You can hire a marine biologist to join your tour and educate you throughout the experience with some tor providers.  Be sure to ask if you’re interested
    10. Whale shark tourism in Donsol grew with cooperation from the World Wildlife Foundation offering advice and guidance for staying eco friendly
    11. Only snorkeling is allowed in Donsol on the main “whale shark experience circuit” – though there are dive sites where whale shark interactions may happen near Donsol
    12. Stats on the whale shark
      • The maximum size of the whale shark is unknown, but could be as much as 20 meters (~60 feet), although, there have been  unofficial reports of 30 meter (~90 feet) long whale sharks.
      • Average length of mature whale sharks is 40 feet
      • Average weight of mature whale sharks is 11 tons
      • Whale sharks feed on the surface but adults may dive as deep as 1000 meters
      • Average mature weight
      • Feeding habits
      • Population size
    13. The Whale sharks skin patterns are completely unique, like human fingerprints – no two patterns are alike
    14. Tourism in Donsol evolved from originally hunting whale sharks
    15. Whale sharks are currently an endangered speciesThough protected in some countries, whale sharks are still a target of commercial fishing operations.  Hundreds of whale sharks have been killed in China for fins, skins, and oil. Awareness and education are the best options for reducing the negative impacts humans have on the whale sharks.  For this reason,even questionable operations (such as swimming with whale sharks in Oslob) stand to provide more benefit than harm to the whale sharks
    16. Whale shark tourism is contributing heavily to whale shark conservation and community development in the Philippines
    17. Taking a freediving course before swimming with the sharks will make the interaction much better.  A basic freediving course will get you to the point of holding your breath for 2-3 minutes and diving to depths of 20 meters / ~60 feet without SCUBA gear.  This will enable you to swim down, under, and around the shark, making the most of the experience.  I did a freediving course before my whale shark experience and the ability to swim, dive, and stay underwater made the experience unreal.
    18. The Philippines was one of the first countries to adopt legislation protecting the whale shark, making it illegal to touch, fish, or harm the whale sharks in any way and punishable by fine or prison time
      1. Source:
    19. “Interactions” with the whale shark are regulated by the Donsol Department of Transportation office and include limiting the number of people per boat, limiting the number of boats in the water, and requiring a minimum distance of 3 meters between swimmers and the shark

    To swim with whale sharks or to not to swim with whale sharks: The choice is yours, but getting educated and spreading the word is best for the whale shark and the oceans.

    What to Expect in your Donsol Whale Shark experience

    After registering, with the visitor’s center or your tour provider you’ll be directed what time to arrive in the morning.  Don’t forget your towel and a dry top to stay warm with the cool sea air blowing by after you get out of the water.  Once everyone is accounted for, you’ll climb onto the boats and head out to see.

    Boat types will vary, but expect one of the Filipino style outrigger boats, equipped with a salty crew.  Once you all have loaded up you’ll be heading out to sea.

    Some of the crew members will be dedicated to spotting whale sharks, just as these fellas are.  As the boat cruises along and you enjoy the fresh air, they’ll keep their eyes out for dark spots in the water in areas where the sharks are known to surface and feed.

    When a whale shark is spotted, you’ll be told to gear up and your captain will head straight for the whale sharks.  The captain will aim to drop you just ahead of the shark, in the direction the whale sharks are swimming or up current.

    This way, the whale sharks will naturally swim right by you before diving giving you maximum interaction time with minimal swimming.

    Once the sharks are gone, you’ll get back onboard and repeat for a few hours or until you and the crew are satisfied…whichever is shorter.

    If you’ve booked a tour through an agency and are lucky enough a marine biologist may be on board to provide commentary.  In all cases, this scientist will share information as it comes to mind and be open to answering any questions.  Some of the biologists have been known to jump in with you as guides also allowing them to explain events or whale shark behavior (that you all may have observed) after getting out of the water.  The Buntanging Interaction Officer (BIO) may also jump in the water too, with the goal of observing and enforcing rules.

    Do keep in mind that the second one boat finds a whale shark, all other boats will be following after shortly, so don’t expect to have the shark to yourself forever.

    Do keep in mind that a whale shark interaction is not guraranteed.

    The Rules of Interacting with Whale Sharks

    • Stay at least 3 meters from the whale shark
    • Do not touch the whale shark
    • Do not wear sunscreens or bug repellants in the water
    • No SCUBA diving or motorized vehicles (SCUBA scooters, jet skis) used in the interaction
    • Stay 5 meters from the whale sharks tail

    • Max recorded Length: 18 meters / ~55 feet
    • Unofficial Max Observed Length: 30 Meters / ~90 feet
    • Average Weight: 11 tons
    • Max Dive Depth: Up to 1000 Meters for adults
    • Diet: Zooplankton (microorganisms)
    • Pupping (birth) has never been observed and pups are also rarely observed
    • Max length: unknown
    • Average lifespan: unknown

    Whale sharks are very mysterious because of two factors.  First, most of their lives are spent at depth, beyond where humans can follow easily.  Second, these creatures are nomadic, known to travel thousands of miles follow food, natural patterns of life, and other unknown factors. 

    The point is, we as people just can’t keep up with whale sharks…which is why they remain a mystery

    The Story of Donsol: How this fishing town became an eco-tourism mecca

    Once upon a time, Donsol was simply a poor fishing village, lackluster and with most its residents living near the poverty level.  During that time, and as early as 100 years ago, whale sharks were viewed as an opportunity to fish and a jackpot payday.  Weighing in at nearly 11 tons on average, a single whale shark could bring years’ worth of income for a poor fisherman.

    In 1998, with the ratification of the “Philippines Fisheries Code of 1998” it became illegal to hunt, catch, or harvest whale sharks (and manta rays), dead or alive.  With this change, the fishermen had to adjust their habits to survive. 

    Around the same time, a group of SCUBA divers swam and interacted with a Donsol whale shark, getting footage of the experience.  The video showed that whale sharks were docile by nature and that the experience of swimming with them was safe, very achievable, and immensely enjoyable.  The former whale shark fishermen, who once used spotters to locate whale sharks to hunt, now used their skill of hunting whale sharks to locate them and facilitate eco-tourism interactions.

    The world wildlife foundation caught wind of the activities and offered their support and mentorship in developing the Donsol whale shark tourism into the sustainable, eco-friendly operation it is today.

    The Donsol whale shark operation has contributed much to finance development, social programs, and investment in marine conversation and protective activities for endangered whale sharks and manta rays as well as other marine life near Donsol.

    The World Wildlife Foundation’s involvement in Donsol Whale Shark Tourism

    Since the first organized and publicized whale shark interactions ~1998 and the passing of Philippine laws protecting whale sharks in 1998, the World Wildlife Foundation has actively supported the Donsol eco-tourism operation.  Their goal has been

    The Debate of Donsol vs. Oslob: Which should you go to and why?            

    Though you can swim with whale sharks in Oslob for far cheaper, Donsol’s tourism operation is unquestionably positive, leaving little doubt the operation results in a “net positive” outcome.

    Dosnol’s guide teams and Buntanging Interaction Officers (BIOs) ensure that a limited number of boats are in the water, with a limited number of swimmers, and that all swimmers stay at least 3 meters from the shark – any violations will result in fines or prison time.

    Though Oslob’s tourism activities are growing it has yet to fully enforce limits for the number of boats in the water and the number of swimmers allowed for each interaction.  The interaction area, a ~20 meter circle, can be crowded with countless boats and flailing swimmers, make the experience less than enjoyable for some.  Also, plan on being very early (4:00AM) if you have any hope of beating the crowds in Oslob

    Outside of regulation and enforcement, the main reason to go to Donsol over Cebu is that it is completely natural.  Whereas in Oslob, Cebu, sharks are baited into warm, shallow waters, where they rarely spend time naturally instead staying in the cooler waters further out to sea.  The Donsol team merely follows the sharks, avoiding any actual interaction, and facilitates observing them in the water.  This approach results in no change to the habits of whale sharks (e.g., where they eat, where they live, how they interact with boats) which is the primary criticism of the Oslob operation and the argued benefit of the Donsol operation.

    If you can afford the extra money, head to Donsol to encourage truly sustainable tourism that doesn’t disrupt the whale shark’s way of life.  The mayor of Oslob has spoken of increasing the price of the interaction to limit the number of participants so hopefully the tourism industry in Oslob will continue following in Donsol’s positive footsteps.

    If Donsol is out of your budget, I still recommend going to Oslo but please read “Why I DID Swim with Whale Sharks in Oslob” get a perspective on the full picture in Oslob.

    Why do the whale sharks come to Donsol? Rich Food Sources and Great Underwater Topography

    Whale sharks feed on zooplankton which are tiny microorganisms in the water.  These little creatures prefer nutrient rich waters to provide their food as well. The Donsol River, which dumps into Donsol’s bay, delivers the nutrients which attract the plankton which ultimately attracts the whale sharks.

    Additionally, the underwater topography and depth is welcoming to the whale sharks, providing the deep, cool waters they call home in close distance to lush feeding areas rich with plankton.


    How to arrange a tour for swimming with whale sharks

    The cheapest way to swim with the whale sharks in Donsol is to register at the Donsol visitor center in Barangay Dancalan.  It is best to do this in advance, especially during the busy season as the number of boats and spaces on them are limited.  If you decide to simply register the day of, just show up at the visitor center at 7:30AM. 

    You will pay a registration fee of 300 PHP (~$6 USD) as a foreigner and a 3500 PHP (~$70 USD) split between a boat of maximum 6 people.  Each boat will be assigned a Buntanding Interaction Officer to guide the interaction with the whale sharks.

    Alternatively, you can have your hotel or guesthouse book the interaction for you, for a small fee, or go to one of the dive or tourism shops, like Frontier Whale Shark Tours, for a more tailored experience.  These private guided tours usually include a marine biologist that enters the water with you and adds an element of education to the experience.
